1 Claim. l This invention relates to window latches, and moreparticularly to the provision of a window latch for holding a windowsash in definite predetermined positions.

rlfhe usual window which comprises an upper` sash and a lower sashmovable relative to each other is generally provided with a latch forholding the window in a completely closed position. There are manyinstances when it is desired to have the lower sash slightly raised orcracked for Ventilating purposes, and at the same time prevent theentrance of burglars or the like, or to prevent children from fallingout of the window.

It is, therefore, an object to provide a latching device which can beattached to the upper sash and the lower sash to hold a lower sash in adefinite raised position. While devices have been heretofore provided inwindows for holding a lower sash in a definite raised position toprevent surreptitious entrance of persons, such devices have usuallybeen built into the window and are not in the nature of attachments.

It is a further object to providea latching attachment to hold a lowersash in several different raised positions, the device being arranged sothat it can be released only from the inside of the window. There arecountless windows which have no latching means, and the latching deviceherein presented provides means which can be readily attached by meansof a few screws.

A further object is to provide a window latching device of simplestructure, making it easy to manufacture and inexpensive, and enablingit to be sold at a low cost so that it will be available to all classesof persons.

These and other objects are attained by the novel construction andarrangement of parts hereinafter described and illustrated by theaccompanying drawings, forming a part hereof, and in which:

Fig. 1 is a perspective view showing the device applied to a windowsash.

Fig. 2 is a side view showing an element of the device applied to theupper sash of the window.

Fig. 3 is a front view of the structure shown in Fig. 2.

Fig. 4 is a front view of a detent forming a part of the device.

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 4.

Fig. 6 is a sectional view taken on the line 6-6 of Fig. 5.

Referring to the drawing the window latching device is shown to comprisean angle 3, prefer- 2 ably made of stainless steel or similarsubstantial metal, the angle 3 being attached to the bevel side 8 of thesash by means of screws 1 passing through the enlarged portion 6, whichportions are integral with the longitudinal portion 5. This allows aspace between the sash I and the portion 5. On the portion indicated by3, which is at right angles to the portion 5 there is provided aplurality of openings or slots 4, and due to the bevel part of the sashI room is provided on the inside of the portion 3 to allow a plunger topass through the slots 4. In the event the sash has no bevel part 8,washers are placed beneath the portion 5 to give the proper spacing forthe passage of a plunger. v

On the upper horizontal cross piece 2l) of the lower sash 2 is mountedby means of screws passing through horizontal anges I2, a casing havingan upper wall 9 and side walls II, the flanges I2 being integral withthe side walls II.

Integral with the upper wall S is a front wall Ill having an aperturethrough which passes a plunger I5 adapted to enter the slots 4. Fixed tothe cross piece 28 is an angle having a vertical side I3 and ahorizontal side I4, the latter being attached to the cross piece bymeans of screws or the like. A plunger passes through the vertical sideI3 and has a head I6 which engages fork I'I of a handle I8, which isprovided with. a bowed portion IIJ to give leverage to move the plungerbackward against the action of the coiled spring 22 which abuts a disc2l fixed to the plunger I5 and the side I3. In operation, to release thewindow the handle I8 is moved to the right (see Fig. 1) to move theplunger to the right as would be the case as shown in Fig. 6. The windowcan now be moved to various positions as may be desired and the plungerallowed to enter any of the slots at the desired position. In thismanner a window can be positively latched from the inside thereof toprovide various openings from. the bottom of the window to prevent theentrance of burglars or children falling out of the window, and at thesame time enable the passage of air for Ventilating purposes.

It is obvious that the device can be applied to almost any window, manyof which are equipped only with means for latching a window in acompletely closed position.

The device is simple and comprises, obviously, few parts which can bequickly attached to the sashes by means of a few screws. The device isinexpensive to manufacture and can be sold at a very low cost so that itcan be available to persons of all means.

It is made of stainless steel, brass or ordinary steel or any strongmetal.

The above description is to be considered as illustrative and notlimitative of the invention of which modifications can be made withoutdeparting from the spirit and scope of the appended claim.

The invention having been described, what is claimed is:

In a latching device, a first xed plate having an aperture therein, aVsecond fixed plate having an aperture in alinement with and spaced fromthe aperture in the rst plate, a plunger passing through said apertures,a disc on the plungeradjacent the rst plate, a coiled spring encirclingthe plunger and positioned between ltheadiscgand the second plate, ahead on the plunger ,adjacent the second plate, a forked platepositioned "between the head and the second plate, said plunger passingbetween the forks of the forked plate, said forked plate having aportion bent back substantially parallel to the forked portion and thenfurther bent to provide a portion substantially at right angles to theforked portion.
